SF double-shell tank (steel & FRP)

Tank with integrated finishing of FRP layer using spray-up method with automatic spray machine.

The "SF Double-Shell Tank (Steel & FRP)" is a tank with a double-shell structure that incorporates a leakage detection device (leak monitor), using steel plates for the inner shell and FRP for the outer shell. The external pressure from soil pressure and water pressure during burial is supported by SS400 steel plates with a tensile strength of 400 MPa and a tensile modulus of elasticity of 206 GPa. When comparing the strength of SS400 and FRP, the GL-5 FRP has a tensile strength of 500 MPa and a tensile modulus of elasticity of 7.5 GPa, which is lower; however, when combined with SS400, it has been found to be less prone to damage even in soil where it bears external pressure from soil and water. 【Features】 ■ Double-shell structure using steel plates for the inner shell and FRP for the outer shell ■ Tank equipped with a leakage detection device (leak monitor) ■ FRP layer finished in an integrated manner using a spray-up method with an automatic spraying machine *For more details, please refer to the PDF document or feel free to contact us.
